Comment	Post #279785	@Ol: The reason behind my question is some DMM is rated for 20000 counts, so it can only be 16 bits, a 14 bits is equal to only 16384 steps. (more)	—	over 3 years ago
Comment	Post #279785	first, thank you for the extra informations, "theoretically possible" as you expressed this answer the first question. what about the second one? (more)	—	over 3 years ago

Question	—	Digital multimeter display count range The display counts range is one of the digital multimeter characteristics. We know that a DMM is based on an analog/digital converter, and we know too that each ADC has a certain resolution in bits. A 16 bit resolution is 216=65535 steps, log10(65536)=4.8165 digits, so something between 50000 ... (more)	—	over 3 years ago
Comment	Post #279600	@andyaka yes it has the same feed back/loop but in place of the diff amp there is a comparator its crazy. (more)	—	over 3 years ago

Question	—	What is the role of the differential amplifier in a delta sigma converter? A differential amplifier amplifies the difference between the two input voltages but suppresses any voltage common to the two inputs. Based on this scheme adc the differential amplifier is substracting an input with a delayed input and outputing a tiny difference to the integrator and tha... (more)	—	over 3 years ago
Question	—	What is the difference between differential amplifier and differentiator? Since am interested in how a delta sigma modulator works, I need to know what is the difference between differential amplifier and differentiator if there is a difference of course. (more)	—	over 3 years ago
